17-18 FRX/FRM 3.3 User Guide, Rev 04Bridge Forwarding TableThe Bridge Forwarding Table is used to match MAC addresses with Bridge ports onwhich to forward frames. If an address is not found in the table, the frame will be for-warded out all Bridge ports except those configured for native LLC-2.All MAC addresses are in non-canonical (Token Ring) format.As a frame is received, its source and destination MAC addresses will be added (if notalready there) to the table. (If received from a Token Ring, the addresses will be bit-swapped [described under "Host MAC Address" on page 8-23] when added to thetable.) The FRX/FRM software contains a set of reserved MAC addresses that areconsidered "static," and will always be in the table. The remaining entries are con-sidered "dynamic," and will remain in the table for the time period configured as theBridge Aging Timer in Bridge Node Defaults (described on page 13-5).Press [B] at the Bridge Status Displays Menu to display a forwarding table for all MACaddresses received on Bridge ports in the node.Figure 17-9 Bridge Forwarding Table Display[C],[F],[D],[B] from Main MenuPressing [F2] will update the display. (It is not updated automatically.)Pressing [F4] will allow you to delete all dynamic entries.
